Application filed'September 24,, 1909. Serial No. 519,340.

E. CLARK, a residing at Memphis, in the county of Sicotland and State,of Missouri, have invented certain new and useful Improvements inBearings, of which the following is a specification, reference being ingdrawing.

This invention relates to bearings for shafts and the principal objectof the same is to provide a cage bearing which surrounds a shaft andadapted for use in connection with a journal box, the bearing rollersbeing arranged so that each will be absolutely independent and at alltimes retained in position to prevent frictional contact of the saidshaft with the journal box.

In the practical application of the invention it is contemplated formingthe imairs of end plates the members. of each pair of plates avingbearing balls interposed between-them, the

inner member of each pair of end plates Be it known. that I, ARTHURhaving its inner face provided with an amsaid plates being adapted to ashaft serving as end sup ports for a plurality of cylindrical rollerswhich are retained in spaced surrounding relation to the said shaft, aidrollers being adapted to retain in spaceid relation larger nular groove,

cylindrical rollers which are inter osed be:

tween the said shaft and the journa box.

It will be understood, of course, that in carrying oulnthe obje ts ofthe invention general y stated above, the essential features thereof arenecessarily susceptible of changes in details and structuralarrangements, certain preferred and practical embodiments of which areshown in the accompanying drawings, wherein Figure 1 is a view showingthe bearing adapted for a tapering journal box. Fi 2 is a verticaltransverse sectional view ta on on the line 5-5, of Fig. 1. Fig. 3 1s asimilar view taken on'the line 6-6, Fig. 1. Fig.

41- is another similar View taken on the line 7-7, Fig. .1. Fig. .5 is adetail perspective view of the inner member of the outer air of endplates. Fig. dis a similar view of'the inner member of the inner pair ofend plates.

In the accom anying drawing, the improved bearing as been shown appliedto had therein to the accompany-' for the ends of a thehub and axle of avehicle wheel, but a will, of course, be readily understood that I thesame isbut one of the many uses of the same.

Referring to said drawings by numerals, 1 designates a hub, 2 the usualboxing thereof, and 3 the axle spindle. i 1

The improved bearing forming the subject-matter of this invention iscomposed primarily of end plates looselyfitted around the axle andarranged .in pairs, the members 4 and 5 and 5 of which arecomplementally grooved on their faces to provide an annular ball race 6for the antifriction balls 7. The inner members 5 and 5 of each air ofend plates are preferably thicker t an the outer member 4 and are eachprovided on its inner face with an annular roove 8 plurality of eongatedich are held in spaced surrounding relation to said axle, spindle andthe hub box 3 by said groove 8. Each of these members 5 and 5 isrespectively. concave and convex on its inner face so that it willconform to the angle of the endsof the large taperin rollers 10 Apluralityof cylindrical ro lers 10 which are larger in diameter than thetapering rollers S are;

tapering rollers 9 w fitted betweerr the inner plates 5 and rest in;

contact with the hub box and the axle' spindle, each tapering roller 10being'spaced from the adjacent roller by the tapering rollers 9, thearrangement being such that;

each tapering roller 10 may rotate independently.

a It will be seen from the foregoing that all parts of the improvedhearing may be read ily separated, as the same are retained in;operative relation by the parts of the; hub

and spindle'to which they are applied;

As will beundersl pod, the tapering rollers l0 are the main an ifrictiontapering rollers of the bearing and they are loose between theinnerplates 5 and 5 and are retained .in spaced antifriction relation bythe smaller interposed tapering rollers 9* which are. r0

tatably supported in the annular groove 8.

It will also be understood that the end lates.

4-4)". and 5 are loose on the axle spindle. This described manner ofmounting the roller bearings and also the plates, permits the members ofthe bearing to be entirely independent, so that the bearing will stillperform its friction overcoming functions in nally about said shaft, emispacing-tapering the event 021? any of the parts thereof becoming jammedor clogged.

What I claim as my invention is A bearing for shafts, comprising ashaft, pairs of plates loose thereon, each pair of plates having anannular groove in their adjacent feces, balls in said grooves, one ofsaid plates being convex and the other eoncave on the adjacent faces ofsaid plates, the inner plate of each of said pairs of plates having anannular groove on its inner face, tapering bearing rollers locatedlongitudirollers located longitudinally about said shaft alternatingwith the tapering hearing rollers and having their ends loosely-mount edin the inner annular groove of the inner loose plate.

In testimony whereof I hereunto afiix my signature in presence or twoWitnesses.

ARTHUR CLARK.
